I know the manuals say you need specialist equipment to create a hydraulic lock to fix the point of injection to time these DPA pumps properly, but I've never seen it done. To remove the Rotary CAV DPA injection pump from Ford 3 and 4 cylinders. Torque Value: 10 n.m 89 in-lb Pump Timing - Lucas CAV DPA, Stanadyne DB4, Delphi DP210, Nippondenso EP-9, and Bosch® P7100 Rotate the engine to top dead center (TDC). Cav Dpa Timing Marks Off In reality the only difference in any 3 cylinder Ford using a CAV DPA pump is the cam ring settings for maximum delivery and that would have no bering on your high idle problem.
However, Bob’s tractor has the circlip mark on the hole above the circlip gap. Bob has followed the 23C Engine Rebuild DVD and notes that on the DVD it shows the circlip mark on the lower side of the clip gap. We’ve had a query about aligning the letter G against the circlip mark when timing the fuel injection pump on the 23C engine. See what the timing marks are supposed to look like for the injector pump, camshaft, crank, and idler gear on a Perkins 4.236 Diesel Engine in HD. You wouldn't have to move the crank but a few degrees to be off a tooth. When I built my engine the #1 piston was all the way up, the timing marks on the balancer were lined up, the lifters for cylinder 1 were all the way down, and the dots lined up on the timing chain.
Somehow when you lined up the dots on the timing set you was off one.
